This is not in any way a mental illness or a cause for concern. We're attracted to what we're attracted to. As long as it's not hurting anybody, it's fair game. Check out any porn site. Look at the all the sick, crazy categories and ask yourself if thongs is a problem. Gang-bang, teens, bestiality domination, incest, steps, rape fantasies, men in women's panties, women peeing, foot sex...good grief. Humans are weird, sick people! For every oddball fantasy there is a porn site to give it to you. We are so hard on ourselves, though. We like what we like. Even if you were turned on by wearing women's thong underwear, not a one would judge you here. Some chicks even dig it.
